Temperate, lowland to montane base-rich scree

Description (English)

Screes of mostly coarse, unstabilized material derived from calcareous and dolomitic bedrocks in the lowlands, foothills and sub-montane zone of temperate Europe. Vegetation can be completely lacking, but rock surfaces can have bryophyte and lichen communities and, where crevices accumulate soil, the vascular plant component can be diverse and lush. Natural succession following stabilization of screes allows encroachment of shrubs and trees, vegetation not included in this habitat.

Indicator species

Diagnostic species
Constant species
Dominant species
Flowering Plants Galeopsis angustifolia

Diagnostic species occur concentrated in the habitat in question, but are absent or rare in other habitats. They are good positive indicators of the habitat, but they do not need to occur in every location of the habitat.

Species scientific name English common name Species group
Galeopsis angustifolia Flowering Plants
Flowering Plants Vincetoxicum hirundinaria
Flowering Plants Galeopsis angustifolia
Flowering Plants Euphorbia cyparissias

Constant species occur frequently in the habitat, but they may include generalist species that are also frequent in other habitats.

Species scientific name English common name Species group

Galeopsis angustifolia Flowering Plants
Euphorbia cyparissias Flowering Plants

Dominant species are those that often reach high cover in the habitat, thus determining the habitat physiognomy.
